To all 1071 0122, itmay concern:

Be it known that I, HENRY-O. MILLER, of

.Milwaukee, in the county of Milwaukee and State ofW'isconsin, haveinvented a new and useful Improvement in Temporary Binders,

of which the following is adescription, refer ence being had to theaccompanying drawings, which are a part of this specification.

My invention has relation to improvements in temporary binders.

, The invention relates more particularly to that class of binders inwhich leaves are placed and secured between the side pieces accommodatethe increased number of leaves.

- The invention also contemplates as an object an improved form oflocking mechanism.

With the above and other incidental objects in view the inventionconsists of the devices and parts or their equivalents, as hereinaftermore fully pointed out.

In the accompanying drawings, Figure 1 is a perspective view of atemporary binder involving my invention. Fig. 2 is a plan view of theupper plate, the leather or other covering being removed, and alsoshowing a fragment of the lower cover-section of the book. Fig. 3 is afront view of the plates constituting the frame, portions being brokenaway, the figure being a view at right angles to Fig. 2. Fig. 4: is aview of two of the removable posts Fig. 5 is a view showing a form ofremovable post which is adapted to be. turned freely in either directiontoa limited extent, the view being a horizontal section through the postand looking down upon one of the leaves of the book and upon the upperside of the lower cover-section. Fig. 6 is an elevation of the form ofconstruction shown in Fig. 5. Fig. 7 is a sectional View through themetallic plates, showing the removable post as consisting of telescopingsecbinding-strip 10.

tions; and Fig. 8 is a View through the upper telescoping section of theform of post shown in Fig. 7, looking down upon the lower cover- 5 5 Thenumeral 11 indicates the other cover section, provided at its rear witha similar ploy posts 14, which have their lowerends threaded. Thesethreaded lower ends are adapted to engage threaded openings in one ofthe binding-strips of a cover-section. As is well understood in thisclass of inventions, the rear binding-strips are usually composed ofmetallic plates which are covered by leather or other suitable covering'In the illustration of my invention I prefer to show such plates,although I wish it distinctly um derstood that I do not limit myself tothe use thereof, as the omission of such plates is within the spirit andscope of my invention, and the binding-strips 10 and 12 may be formed ofany suitable material. The lower metallic strip is indicated throughoutdifferent views of the drawings by the numeral 15, and the uppermetallic strip by the numeral 16. The lower threaded ends of the posts14 in the form of construction shown in Figs. 1 te l are shown asengaging threaded openings 17 in the metallic strip 15, while the upperstriplfi is provided with plain or unthreaded openings 18, through whichthe posts are adapted to pass. The upper ends of the postsiare'advisably formed with nicks for the engagement therewith of ascrew-driver, so that. after such a quantity of leaves has beenadjustedbetween the cover-sections the lengths of the posts will notpermit the insertion of additional leaves. These short posts may beturned until their threaded ends are disengaged fromthe threadedopenings 17, thereby permitting these posts to be removed and longer pot Fig. iof the drawings openings 19 in the leaves 13, and I prefer thatthe leaves'be formed with slots 20, extending fromthese openings to therear edge of said leaves, so as to provide for the leaves being readilyremoved when desired. If re ferred, however, merely round openings intheleaves may be provided.

In Figs. 5 and 6 of the drawings I show a form in which the postindicated by the numeral I I is not only removable,'but also revolublein either direction. To accomplish this function, I provide the lowermetallic strip with unthreaded openings 21, in each of which is fitted asleeve 22, said sleeve formed with top and bottom flanges 2328', whichembrace the metallic strip. The sleeve is interiorly threaded, and thelo'we'r'threaded end of the post is adapted to be turned therein. Ifdesired, the extent of the-turning of the sleeve 22 may belimited bymeans of a pin 24, extending downwardly from the under side of themetallic strip15, said pin being adjacent to a cut-out portion 25 in theperiphery of the bottom flange 2 3. It will be evident that theshoulders formedat opposite ends of the cut-out portion will contactwith the pin 24, and thereby limit the extent to which the sleeve can beturned in either dimotion. This construction of flanged sleeve is thesame as that covered in the United States Letters Patent issued tomyself and Julius Bauer on August 10, 1897, No. 587,986,

.for improvements in temporary binders, it

being'illu'strated on the drawings of the present invention in order toshow that a removable post can be applied thereto so as to make the postboth removable and revolupost.

ble. The sleeve covered in the Letters Patent aforesaid, however, wasmade a part of a section of a telescoping post and did not have athreaded connection with the section of post, as in the presentinvention.

The form of post preferably used in the arrangement shown in Figs. 5 and6 is a post oblong in cross-section, so that when the post is turned soas to present its greatest width across the opening 19 of the leaf,which greatest width is greater than the width of the slot 20, the leafis locked in place, whereas if the post is turned so as to present itsgreatest width in line with the slot 20 the leaf can be readilywithdrawnfrom engagement with the It will be obvious, however, that in this formof construction a post round'in crosssection may be employed either inconnection with a leaf having merely a round opbningor a round openinghaving a straight slot extending therefrom and satisfactory results secured. The construction shown, however, is preferable. fact that in theconstruction shown in Figs.

1 to 3'an oblong or similar form of post could alsobe employed insteadof the round form shown, especially when leaves are used having openingstherein for the reception of the Attention is also calledto thethread soas to bring, its greatest width in line-with the ,slot 20. H

In Figs. 7 and 8 I show the application of my invention to a telescopingpost, whereby a lengthening to a certain extent is effected by theraising of one post within the other. I show a tubular section 26,having a lower threaded end engaging the threaded opening 17 of thelower metallic strip 15 and an up the'lower section therewith, so thatboth sections together will be disengaged from their respective threadedopenings. When the upper cover-section has been raised to such an extentthat the lowerend of the upper-postsection 27 is almost out of the boreof the lower tubular section, it then becomes necessary to remove thetwo sections and substi- The upper extremity of section.

tute others of greater length, which of course is accomplished in themanner just pointed out. \Vhile it is preferred in this form ofconstruction where telescoping post-seetionsare employed thatbothsections be removed, yet it is obvious that successfulresults mightbe obtained by merely making one section removable. Again, while in thedescription of this form of device I have described the two sections ofthe post as of oblong shape" in cross-section, yet, if preferred, theyneed not necessarily be of this particular form, but may be square orrectangular. In fact, round sections may be employed, if desired. In thelatter instance, however, some suitable means should be provided forcausing the lower tubular section to turn with the upper section whenascrew-driver or other turning tool is applied to said upper section. Iwould also call attention to the fact that, ifdesired, in the form shownin Figs. 7 and 8 the lower tubu-' lar post-section may-have a threadedconnection with'aprevoluble sleeve, such as that shown in Figs.. 5 and6. In such case, therefore, I would thereby provide removabletelescoping and revoluble posts.

. While any suitable locking mechanism may .be employed for holding oneof the cover-seccess 30. In this recess is slidingly mounted the ward ofakey inserted through the keya bolt 31, one end of said bolt beingpivotally y the strips'29 is thereby relieved, so that the form. Thebelt is also formed on .one edge connected to the inner ends of two arms32 32, the three parts forming a toggle-joint. The outer ends of thesearms are fitted in recesses 33 33in the metallic strips 29, the ends. ofthe arms being preferably rounded and the recesses being of acorresponding with oppositely inclined or beveled surfaces 34 34, whichare adapted to be engaged byopening 35. When the key is passed throughsaid opening and turned in one direction, it will act on the inclinedsurface 34 and shoot the bolt in one directiomso as to thrust thepivoted ends of the arms 32 toward theedge of the strip 16. This willforcethe ends of rection to force the-strips 29 outwardly and cause theedges of the openings 36 36. of said strips to bear firmly against theposts 14, said posts passing through the openings referred to. By thismovement it is obvious that the upper cover-section is maintained atadjusted position. When the key is turned in an opposite direction, soas to act against the beveled surface 34, the bolt 31 is drawn inwardly,and pressure of the arms 32 against cover-section may. be readilyadjusted to another position. It will be noticed that the openings 36are of such greater diameter than the posts 14 as to permit slight playof the plates 29, and thereby make it possible forsaid plates to bemoved to locking position, as just described. The strips 29 are held tothe strips 16 by means of screws 37. These screws pass through plainopenings 33in the strips 29, which openings are also of such greaterdiameter than the screws as to permit of a slight play of the strips 29.also be noticed that the bolt 31 is provided 1 It will on one edge witha recess 39, into which recess a pin 40 extends. When the bolt is moved,this pin contacts with the shoulders formed at the ends or the recess39, and thereby limits the extent of the movement of the bolt in What Iclaim as my invention is.--

.either direction. The toggle-joint-locking mechanism is advisablycovered by a plate 41.

F1. The combination, of longitudinal strips,

-a threaded end fitting the internal threads of the sleeve, and saidpost or posts entering I the opening or openings of the otherlongitudinal strip.

2. In a temporary hinder, the combination,

of parallel longitudinal strips, posts extending from one of said stripsand through openings in the other strip, short strips superimposed uponthe last-mentioned strip, said short strips having their, inner ends adistance from each other so as to leave a space therebetween, and. saidstripsprovided with openings through which the posts pass, the openingsbeing of such greater diameter than the posts as to permit of a slightmovement of the strips, a bolt seated on the longitudinal stripin thespace between the inner ends of the short strips, arms pivotallyconnected to the bolt and having their outer ends engaging the ends ofthe short strips, and means for actuating the bolt.

In testimony whereof I afiix my signature in presence of two witnesses.
